Sine Theta (sin θ) = opposite/hypotenuse = a/c
Cosine Theta (cos θ) = adjacent/hypotenuse = b/c
Tangent Theta (tan θ) = opposite/adjacent = a/b
Cotangent Theta (cot θ) = adjacent/opposite = b/a
Secant Theta (sec θ) = hypotenuse/adjacent = c/b
Cosecant Theta (csc θ) = hypotenuse/opposite = c/a
You may need to look on the link below for some sample calculations
There are three types of trigonometric functions, they are: 1- Plane Trigonometric Functions 2- Inverse Trigonometric Functions and 3- Hyperbolic Trigonometric Functions
trigonometric table gives the values of all the trigonometric functions for any angle. i.e; it gives the numerical values of sine, cosine, tangent etc for any angle between 0 to 180 degrees the values for other angles can be calculated using these.
There r 6 trignometric functions,namely sin a cos a tan a cosec a sec a cot a where a is the angle. Trigonometric functions didn't exist without angles.
The sine and the cosine are always less than one.
TRIGONOMETRIC FUNCTIONS OF ANY ANGLE
In geometry, similar shapes have the same angles. This means that the values of the basic trigonometric functions of these angles are the same.
With ease, I suppose. The question depends on what you consider easy trigonometric functions.
There are several topics under the broad category of trigonometry. * Angle measurements * Properties of angles and circles * Basic trigonometric functions and their reciprocals and co-functions * Graphs of trigonometric functions * Trigonometric identities * Angle addition and subtraction formulas for trigonometric functions * Double and half angle formulas for trigonometric functions * Law of sines and law of cosines * Polar and polar imaginary coordinates.
You can use them to find the sides and angles of a right triangle... just like regular trigonometric functions
